Description

i 1 FOUR-WHEELED T-HANDLEBAR INVALID CARRIAGE
BACKGROUND OF THE INVENTION
223721 The present invention relates generally to a carriage for the senile and the invalid and particularly to a carriage which is operated with the T- shaped handlebar and stablized with the device of four wheel.s.
So far, all other types of carriages for the senile and the invalid have been proposed to be threewheeled, though with T-shaped steering handlebars as well. Such a three-wheeled carriage, however, often caurzes difficulty in maintaining balance for an aged or invalid rider, who is constantly endangered, for instance, by the carriage's overturning.
With the foregoing in mind, it is an object of the present invention to provide a convenient and safe four-wheeled T-handlebar invalid carriage which viorks with extraordinary stability while moving.
SUMMARY OF THE INVENTION
The objects and advantages of the present invention will appear-as the description proceeds when taken in connection with the accompanying drawings, in which
Fig. I is a view of the outlineof the fourwheeled T-handlebar invalid carriage.
Fig. 2 is a perspective view of the invalid carriage when assembled.
Fig. 3 is a perspective view of the various parts of the invalid carriage when disassembled.
Fig. 4 is a sectional view of the seat of the invalid carriage, illustrating the rotary movements of the seat.
As shown in Figs. 1-4. the four-wheeled Thandlebar invalid carriage includes-a dynamic device I installed underneath a seat 2 and above a seat stand 4, powering a motor 12 by means of.a battery 11 (i.e. storage battery). The carriage is driven by rear wheels 31 and 32 when a chain 14 connects a differential 13 installed between the rear wheels to a gear 121 of the motor 12.
A T-shaped handlebar 5 consists ot a supporting rod 51 and a slant steering rod 52. The tooth surface S11 at-the lower end of the supporting rod and that S21 at the upper end of the slant steering rod are interlocked i i 1 11.
1 3 j tightly with a screw 53 ano a nut 54, so that the two S1 and 52 can be assembled. By loosening the nut 54 and thereby rotating the tooth surfaces 511 and 521, L.he rider can adjust the handlebar 5 to a position most suitable for him/her to hold and make the best use of the space as well.
A device 6 is to restrict the angle of frontwheel oscillation. The bottom part of the slant steering rod 52 in inserted into a sleeve 61 of the. device 6, welded fixedly to a link rod 35, and thereby connected "c link 341 which is connected to a front- to a plat wheel 34 and is welded to the link rod 35. The Tchaped hiandlebar 5 is therefore being steered to conLrol and adjust the angle of fronL-wheel 33 and 34. The front-wheccls 33 and 34 are placed separately at the two ends of a horizontal rod 42 and connected to plate links 331 and 341; a link rod 36 in turn connects the trols the angle of plate links 331 and 341 and cont front-wheel oscillation.
The device. which controls the angle of front wheel oscillation, is supported by a shaft 611 of the Lk sleeve 61 and is Yielded fixedly to a ver'tical rod 41 of the scat stand 4. Attached to the opposite sides of the slnevn 61 are rods G12 and 613 which are to restrict the tilting of the horizontal rod 42 of the scat stand 4. When one of the front-wheeld 33 and 34 at the two ends of the horizontal rod 42 tilts because of the rough road surface, the according rod, that is. either rod 612 or 613. begins restricting the tilting movement and prevents the carriage from overbalancing or overturning.
Seat 2 comprises an adjustable rotating device. A main shaft 21 extends from the bottom of the seat 2; the main shaft 21 in inserted through a disc 22 and into a sleeve 23 and is fixed on the seat stand 4. A pulling rod 24 penetrates the rear of the main shaft 21; one end of a spring 25 is fastened to the end 241 of the pulling rod 24, and the other end of the spring 25 is fastened to the bottom of the seat 2. Pulling the rod 24 upward in accordance with grooves 221 circularly patterned on the disc 22, the rider may rotate and adjust the scat 2 to a proper angle, and 1 i to fix the seat 2 the rider needs only to release the pulling rod 24 and lock its protuberant block.242 inside a goove 221. Such an adjustable rotating device as the seat 2 makes it a convenient drive for those who have difficulties in getting aboard or alighting from the carriage.
The foregoing description and the drawings,e!re given merely to explain and illustrate the invention and the invention is not to be limited thereto, since those skilled in the art who have the disclosure before them will be able to make modifications and variations therein without departing from the scope of the invention.
